This is a really bugging one: I am writing a document in Dutch language, and from the moment I start typing, the proofing language changes into English, mentioning that I am writing nothing but errors.
As mentioned on Office support, I have set the proofing language as "Dutch (Belgium)", but this does not solve my issue.
In the Language preference, I have removed "English (Belgium)" from the list (English is not a Belgian language, so how can you have an "English (Belgium)" proofing), but after having restarted MS Word, the "English (Belgium)" just reappears in the Language preference and when starting typing, the proofing language changes immediately to "English (Belgium)".
Sorry for sounding so frustrated (but I really am), does anybody know how I can get rid of a proofing language so that it never appears again? (I've just checked "Add and Remove Programs" and I don't find any language references)
I'm working with Microsoft Word 2016 MSO 32-bit.

You have to change your "default input language" to the language you want Office to spell check as default. (Win7: Start > Control Panel > Change keyboards or other input methods > Change keyboards... > Select language in dropdown menu.)
I am aware that this is not a real solution to your answer but apparently there is no good fix. This is a bug in Office which is described here: https://support.microsoft.com/en-us/help/292106/changes-to-default-language-settings-are-not-retained-in-word
